Cosmic Ray e-Lab Logged in as group: fermigroup LogoutMy Logbook

Join a national collaboration of high school students to study cosmic rays.

Why cosmic rays?

Spending all your time in a shower ?

When you're sleeping or sitting in class, cosmic rays shower the earth andeverything on it.

What are cosmic rays ?

Where do they come from ?

Where do they hit ?

Some cosmic rays have so much energy that scientists are not surewhere they come from. A number of reseach projects are looking at thisquestion.

Who are we?

We're a collaboration of high school students and teachers collecting andanalyzing cosmic ray data to answer some of these questions. We'reworking with computer scientists to provide cutting edge tools that usegrid techniques to help you share data, graphs, and posters andcollaborate with other students nationwide.

Who can join?

You ! Think about steps you'd take to investigate cosmic rays. How wouldyou get started? What do you need to know? Can you collect and usedata?

Transformations & Derivations

Transformations stitch together code into one workflow for local or grid execution.

Derivations invoke transformations with specific inputs, like a function call.

Scaling = Rethinking Our Original Design

The Cosmic e-Lab started as a pilot program with primary focus on a working model.

Now, we aim to support new e-Labs using the same tools, look and feel, general architecture, etc.

CMS test beam data and LIGO are currently in development.

Currently DevelopingCMS e-Lab using test beam and ROOT

Join a national collaboration of high school students to CMS test beam data.

How small is small?

How small is so small that we can get no smaller ?

Why do objects have mass ?

How do scientists "see" particles much smaller than an atom ?

Understand how a 12,000 ton detector "sees" electrons, muons andother particles.

Who are we?

We're a collaboration of high school students and teachers analyzing datafrom the Compact Muon Solenoid Collaboration, CMS, experiment at CERNin Geneva, Switzerland to answer some of these questions. We're workingwith computer scientists to provide cutting edge tools that use gridtechniques to help you share data, graphs, and posters and collaborate withother students nationwide.

Who can join?

You ! Think about steps you'd take to investigate particle collisions at thehighest accelerator energies. How would you get started? What do you needto know? Can you analyze data?

Lessons Learned

Lessons LearnedGrid work is bleeding-edge and harder than it looks.

Professional development for teachers is critical.

Developers must work within technical constraints of schools.

It’s premature to understand how the Grid enhances education.

Computer Scientists learn from e-Labs.
